A CORPORAL LEAF-sUPPORiiFOl-' Asi-tolles OF FURNI'IURQ SPECIFICATION forming part of ,Letters Patent No. 733,046, dated my 7, 1903. Application filed September 17, 1902i lRenewed Tune l, 1903. Serial No. 159,628. (No model.) i

@To all whom t may concern: f

\ Be it known that I, OzELLo R. HUNT, aciti` zen of the United States, residing at Kenosha, in the county of Kenosha and State of "Wisconsin, have invented a new and useful Improvement in Leaf-Supports for Articles of Furniture, of which the following is a speci- 1 fcation.

ically disengaged to allow the leaf to be loweps My invention relates particularly to `autom matically-released supports for the folding leaves of convertible articles of furniture, such as couches and sofasbeds.

My primary object is to provide an automatically-disengaged support for a leaf movable from a horizontal position, as when the article of furniture is used as a bed, to a ver-` tical depending position, as when said article is used as a couch. Y

The invention is illustrated `in the accompanying drawings, in which-QV i Figure l represents a broken View, in end` elevation, of a couch equipped with my improvement; Fig. 2, a broken sectional yiew looking at the inner side of the end frame shown in Fig. 1, and Figs.`3 and 4L broken inner in which the leaf-supports are automatered.

The invention is here shown applied tothe front leaf of a sofa-bed of the'type employing a vertical standing rear leaf or back(not shown) and a vertical depending front leaf.

` The preferred construction is as follows: A represents the swinging front leafof acon- `vertible couch or sofa-bed A,the main frame of said article of furniture; A2, a leaf-snpporting link connected by a pivot A3 with the leaf A; A4, a link-releasing cam carried by the main frame, and B a wire` fabric of any suitable construction applied tol the frame andleaf. The main frame has end standards' (one shown) comprising front vertical members (angle-irons)A5,having rearwardlyturned flanges A6 andinturned iianges A7. The flanges A7 are connected by an an glo-iron A8, having a downturned liange and a rearwardly-turned ange. The ends of this member litfwithin the angles of the Vertical mem- `5o bers A5, and the 'horizontal ange supports `the cams A4., (one at each end.)y Eachcam A4 icomprises a base portion a, a substantially `portion a5, having an oblique inclined edge 01,6 crossing the edge a3, assuming theleaf to be in the extended position. Adjacent to its extremity the link is provided on its lower edge with a notch a", presenting a shoulder as, which serves to engage the flange Alat "the loweil wall of the slot a4 in the extended position of the leaf, and a surface a9, which serves to raise the link when the leaf is raised somewhat above a horizontal to effect a re' lease.

The manner in which a release is eected will be understood readily from Figs. 3 and 4. When the leaf is raised somewhatabove Ythe horizontal position that is indicated in dotted lines in Figs. 1 and 2, the lower ends of the links are caused to rise, as stated, and in their movement the cam-surfaces a6 engage the cam-surfaces d3 and cause the upper portions of the members A4 tospring inwardly till the portions a5 clearthe portions o?, whereupon the members A4 resume their original positions and the portions Va5 ride upon the upper surfaces of theportions a2,

so thatthe shoulders o? are held `out of engagement with the stationary shoulders at the lower walls of the slots a4 as the leaf is lowered. Of course it will be understood that when the leaf is again raised the projections o will pass beneath the projections a2,

so that the links can drop to the lockingposition when the notches a7 reach the proper position.

Changes in details of construction within the spirit of the appended claims may be made. Hence no undue limitation should be understood from the foregoing detailed description.

What I regard as new, and desire to secure by Letters Patent, is

1. In an article of the character described,

with a stationary shoulder, and a swinging leaf connected with said frame, of a link connected at one end with said leaf and provided near its opposite end with a shoulder serving to lockingly engage said rst-named shoulder and provided alsowith a lateral projection, and a yielding cam on the main frame opposed to said projection and over which the latter rides during the release, for the purpose set forth.

3. In an article of the character described, the combination with a main frame provided withy a stationary shoulder, and a swinging leafl connected with said frame, of a link connected at one endwith said leaf and provided near` its opposite end with a shoulder serving tolockingly engage said first-named shoulder and provided also with a lateral projection, and a yielding resilient cam fixed to the main frame and opposed to said projection and which is forced aside when the leaf is raised above the horizontal and over which said projection rides when the leaf is lowered to effec'tfa release.

A5.' In an article of the character described, the combination with a main frame provided with ay guide and a stationary shoulder, and

a swinging leaf connected with said frame, of a link connected with said leaf and provided with a shoulder serving to lockingly engage said first-named shoulder and provided with a laterally-projecting cam, and a spring-metal cam fixed to the main frame and having a lateral projection engaging said first-named projecting cam, for the purpose set forth. l A

5. In an article of the character described, the combination with a main frame comprising end standards and a member connecting said end standards, and a swinging leaf connected with said main frame, of links connected with said leaf and having their free ends extending through suitable guides on said frame, said links having inturned projections, and yielding resilient cams carried by the member connecting said end standards and having outturned projections, for the purpose set forth.

6. In an article of the character described, the combination with a main frame comprising end standards and a member connecting said end standards, and a swinging leaf connectedwith said main frame, of links connected with said leaf and having. their free ends extending through suitable guides on said frame, said links having inturned projections provided with oblique edges, and yielding resilient cams carried bythe. member connecting said end standards and having outturned projections provided with ob,- lique edges engaging said first-named oblique edges, for the purpose set forth.
